Abstract
Planning a trip to unfamiliar public buildings is challenging for people with visual impairments as much visual information such as floor plans is not accessible. Textual descriptions of an indoor map would therefore be very useful to prepare a trip. In particular, an allocentric description independent from the current location of the user which could be used at home would support the preparation phase. However, descriptions of buildings are rarely available. So the main question is how to tailor the descriptions to the needs of people with visual impairments in order to not overwhelm them with too much information at a time. We propose a system for the generation of allocentric textual descriptions for public buildings. In a user study, we tested the usefulness of our system and found that a modular design is regarded helpful to clearly structure descriptions by splitting the description into meaningful modules and avoiding information overload.
